The next day, a duck walks into the bar and says to the bar tender, "I want to buy some peanuts." The bartender replies, "I already told you I don't sell peanuts!" The duck leaves.

The next day, a duck walks into the bar and says to the bar tender, "I want to buy some peanuts." The bartender yells back, "I told you, I don't sell peanuts! If you ask one more time, I'll nail you to the wall!" So the duck leaves.

The next day, a duck walks into the bar and says to the bar tender, "Do you have any nails?" The bartender says, "Sorry, don't have nails." The duck asks, "Do you have any peanuts?"
